SHEEP-SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 301,519, dated July 8, 1884.

Application tiled October 2, 1883.

.To @ZZ whom it may concern:

Be it known thatl we, JOSEPH K. PRIEsT and RoswnLL T. SMITH, citizens of the United States, residing at Nashua, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Shearing-Machine, of which the following is a specification.

Our invention consists of certain constructions, combinations, and arrangement of parts,

hereinafter fully described and specifically claimed, which constitute a machine of novel, simple, and durable construction, and of easy operation, adapted for shearing sheep and other animals. y

In the accompanying drawings, Figure l is a top view of our invention as applied to a pendent drop-rod, which is shown sectioned horizontally, a portion of the cover of the crank mechanism being broken away. Fig. 2 is a vertical longitudinal central section of the comb-plate and shearinglevers, showing one cutter in the rear. y Fig. 3 is a rear view ofthe comb-plate and adj uncts detached from the handle, the pitman being sectioned. Fig. i is a vertical longitudinal 'central section of aV colnbplate and shearing-levers and cutter of a modified construction. Fig. 5 is a transverse section of one of the cutters, and the end portion of the operating presserlever.l Fig. 6 is a vertical central longitudinal section of the handle of the machine, showing the driving-pulley in a reversed position from that of Fig. 1, and exposing the pendent drop-rod by breaking away portions of the belt-guard and drop-rod socket. Fig. 7 is a perspective view of the upper portion of a belt-guard frame and cloth used around the driving-belt 5 and Fig.

- 8 is a perspective view of the drop-rod socket,

crank-shaft sleeve, and lower belt-guard frame.

, A represents a comb-plate of 'ordinary con` struction, having sharpened teeth a and an electricheating-case, A', whichlatter is inserted 'aid of screws e.

(Model.)

When au electric current is caused to pass over the said wires, the ne platinum wire a becomes very hot, and thus warms the combplate sufiiciently to melt any tallow which, during the operation of shearing, may come in contact with it, and would clog the plate if allowed Jfo-loecome set or solid. Two hollow triangular cutters, B, oscillate over and in close contact with the comb-plate. They are provided with slots b, inner oil-pads, b', of porous oil-holding material, and angular end plates, b2, which latter prevent the oil-holding pads from leaving the hollow cutters by way of their open backs. Thus the comb -plate and faces ofthe cutters B, which are in contact with the comb-plate, will be constantly supplied l from the pads with oil, and always be kept well lubricated by'oil held and supplied by the pads, while any possible waste of any lubricating material will be prevented by reason of the said oil-'pads keeping it from flowing away and w asting before it is supplied to the comb-plate and cutters. The slots b are occupied by ribs c, formed on the ex tremitics c of a forked presser lever, C, which'is operated by means of a double bell-crank lever, D. This lever D is,by means of apivot, d, held to an intermediate plate, E, to which the comb-plate A is fastened with the A front arm, d', ofthe lever D extends into a slot, ci, in the front portion ofthe lever G,andis the means of connection between these parts. In the rear of the slot c2 the lever C is divided into two curved arms, c, passing around the pivot d, and having flanges c5 at their ends, which are drawn together by a transverse set-screw, c, by which means a vertical set-screw, ci, passing through the joint ofthe iianges c5, is securely clamp-ed in place. The foot of said vertical set-screw c7 rests in a socket-hole, di, in the lever D, and the middle portion of the lever G bears up against a short arm, d5, of the lever D, which thusserves as a fulcrum between Vthe front extremities, c', and the set-screw c7 of the lever C, whereby the pressure of` the cutters upon the combplate is regulated. The 'arm di' is provided with an anti-friction roller, d, which travels onv the plate E, and prevents friction and wear between the said arm and plate. A shield, e',

fastened to the plate E over the roller d4, protects the sanne against clogging. The leverD IOO is also provided with a side arm, d6, having a slotted head, dl, through which latter a pitman, f, passes; The forward end of the said pitman is provided with screw-threadsf, a pair of nuts, f2, and a leather washer, f3, at either side .of the slotted head dl, and by fastening these nuts closer to the slotted head dl, or farther away from it, a greater' or a less stroke is given to the cutters B. The pitman fis attached to a wrist-pin, f4, on a crankplate, f 5, which is fastened to the main shaft F of the machine. This main shaft F is hung in a bearing, g, which forms a portion of an inner sleeve, G, fitted into thehollow handleI-I ofthe machine, to the other end of which the intermediate plate, E, is suitably fastened. The handle II is provided with a collar, h, over which an arm or hooked plate, g', is so placed as to grasp the inner surface of the collar h, and thus hold the sleeve Gr to the handle, to which it is fastened by means of screws, but allow both the sleeve and the handle to turn independently of each other. The cranlcplatef 5 may be protected against clogging substances by a sheetmetal cover, g2, of suitable construction. A sleeve, G', extends a part of the way into the bearing g and over the shaft F, and upon its outer end an upright socket, g3, is formed, into which the lower end of a pendent drop-rod, I, is inserted. About midway of its length the said socket is provided with a set-screw, g, which enters an annular groove, t', in the aforesaid pendent drop-rod, and thereby prevents the said rod from leaving the socket, while permitting it to turn therein. Directly below the socket g3 a pulley, f, is fastened to the main shaft F, this pulley having a cylindrical surface and sprockets fl. Ailat belt, J, having holes j, coinciding with the sprockets f7, serves to drive the pulley f G. This belt J is driven by another pulley above, which forms, together with the drop-rod I, a portion of a device for transmitting motive power for which a patent was granted to B. T. Smith, October 23, 1866, and which, therefore, is not claimed or described herein. Below the socket g3 an arm, g5, extends downward a little distance below the pulley f, and there supports an oblong frame, y, in a central position with the drop-rod. At a suitable distance above the pulley f 6 another oblong frame, gl, having` an arm, g8, and central socket, g, with set-screw y1", is attached to the drop-rod I. This oblong frame g7 is provided with a flexible cover or housing, g, which is closed at the bottom and open at the top and on one side, but at the latter (open side) the material or fabric is lapped over, as at gu, and thus the vertical division is hidden, and the cover serves the same purpose as if it were made without a division. When the covering g is to be used, the frame gl, to which it is fastened, is moved down on the drop-rod sufliciently to allow the lower frame, g, andpulleyf6 to be slipped through the side opening at g into the cover g, The

frame g7 is then moved up until the covering g becomes sufficiently tight between the frames g gl, and,l is then fastened to the droprod by means of the set-screw gm. The position described is the normal position of cover g, which is only removed when repairs to the machine become necessary. When the machine is set in motion, the lever C is caused to oscillate with the lever D by means of the slot c2, front arm, d', set-screw al, and socket-hole d2, and the cutters B are caused to oscillate around the pivot d and over the teeth a of the comb-plate A by means of the slots b and ribs c. By turning the set-screw c7 the pressure of the cutters B upon the comb plate is very nicely adjusted, and by drawing on the setscrew c6 the set-screw c7 becomes rigid between the anges c5. The modied construction shown in Fig. 4 is especially adapted for the use of one cutter, and in this plan a presserlever, C, is employed, which has a slot, 01, and transverse pin cu. The front end of an operating-lever, D, is tted into the slot o1, and by means of an inclined notch, d1, bears onthe pin ou. The rear part of the lever C is kerfed and provided with the set-screws c c".

In Figs. l and 6 we have shown by full and dotted lines an oil-reservoir, M, having a flexible supply-tube, M', with cock m. This reservoir may be applied to the drop-rod I, or other suitable portion of the machine, and its purpose is to serve as a means whereby thin oil may be flowed over the cutting 'and other contiguous parts of the machine while shearing sheep which have a thick oily, gummy, or sticky substance like pitch in their wool. The oil thus supplied prevents such wool adhering to said parts.

What we claim as our invention, and desire to secure by Letters Patent, is
